5.4.2 DC Loadline Exemption Certification
To permit them to operate independently from their ERRV, DCís require a Loadline Exemption Certificate issued by the Maritime and Coastguard Agency. The Loadline Exemption details the conditions under which the DC may operate. A typical Loadline Exemption may include:
a) Maximum wind/sea state for normal operation, e.g. 30 knots or 3.5m SWH;
b) Maximum distance of operation from the mother ERRV during normal operations, e.g. 10 nautical miles;
c) Maximum continuous working hours for the DC crew, e.g. 4 hours, davit to davit.
Does the fragment mean that the Daughter Craft crew is supposed to work continuously from the moment the davit lowers a boat to the sea to the moment the davit lifts a boat back up on board again.
What do you think?
No, it means they can work no longer than 4 hours, measured in that way (davit to davit)
